Barquette sounds fancy but it just means "boat shaped". This is an easy-make-ahead hors d'ouevre: sear off the lamb and make vegetable garnish the day ahead and assemble just before your guests arrive. Substitute Beligian Endive for the Radicchio di Treviso if you like.
Coarse salt and freshly cracked black pepper, to taste
large bunches radicchio de Treviso (need about 30 leaves)
Fennel fronds or sprigs of dill, for garnish
1. Preheat oven to 450 degrees F.
2. Season lamb with anise and salt and pepper. Add olive oil to hot sauté pan (with oven proof handles) over high heat. Sear lamb loin on all sides, about 5 minutes. Transfer to oven and cook until medium rare, about 10 minutes. Let rest before slicing. Slice into ¼- inch slices then cut into small pieces. Let cool to room temperature. Refrigerate until ready to assemble hors douevre.
